Obama's political arm (again why is a president allowed this?), Organizing for America, is attempting to exploit September 11th (Patriot's Day) by asking Obamabots to call both their state's Senators and tell them to support Obamacare.
It is hilariously badly written and makes outrageous claims like 75% of Americans support Obamacare which is easily debunked here.
To give you an idea of just how sloppy this posting is. It claims "11788427558 people have signed up to attend this event." That's 11 billion Americans. As Jonah Goldberg observed on NRO when this was pointed out, "How dare you suggest that 2.1billion Americans aren't going to support Barack Obama? Have you even bothered to count up all the dead Chicagoans Axelrod has lined up?" (It was less when he first posted it.)
While that number was probably a software glitch.
